San Patricio; The Chieftains with Ry Cooder
It’s a wonderful album. I can play it all day.
This is behind the scenes footage of the recording process for the new Chieftains album SAN PATRICIO, complete with Spanish subtitles. [It came out in 2010]
Wikipedia has more about the history of the San Patricio Battalion, for those who are interested. They include a list of other music, fiction, and films about it.
There are several songs from the album posted at YouTube, but really, you should just get the whole thing.
